Biohazard Protocol
Every expedition is a gamble. Explore procedurally generated underground facilities, recover valuable loot, survive unique monsters, and escape before it's too late.
Descend. Survive. Bring everyone back.
A routine expedition into an abandoned underground facility quickly turns into a fight for survival. The deeper you descend, the less the complex obeys the rules of reality. Corridors shift, forgotten systems come back online, and something in the darkness has begun hunting again.
Play solo or with friends as you explore procedurally generated underground facilities in search of valuable loot. Every expedition presents a new layout, new dangers, and one difficult question:
How much farther are you willing to go before it's too late?
Recover valuable equipment, manage your limited resources, unlock abandoned computer terminals, restore forgotten systems, and decide whether the next room is worth the risk.
But you're not alone.
Every creature follows its own rules. Some hunt by sound. Some wait for you to make a mistake. Others force your entire team to adapt or die. Learning how they behave is often the only way to survive.
